ubuntu-6.06.1-alternate-powerpc
base system install portion
file: //cdrom pool/main/glibc/glibc6_2.3.6-0ubuntu20_powerpc.deb was corrupt
could not download package glibc/
and once
file: //cdrom pool/main/gpm/glibgpmg1_1.19.6/ubuntu20_powerpc.deb was corrupt
could not download package libgpmg/
keep in mind I tried this cd multiple times
tried different install commands instead of the default, tried oem, oem-powerpc, check, check powerpc, etc.
